  • Remineralizing dental cements
    Patent number: 7619016
    Abstract: Remineralizing dental cements contain source(s) of calcium and phosphate ions, adhesive resin monomers, reinforcing base resin monomers, and catalysts able to initiate the polymerization of the adhesive and reinforcing base resin monomers. Such dental cements can be used as orthodontic cements, crown and bridge cements, adhesives, sealants, cavity liners, and protective coatings. The release of calcium and phosphate ions and, optionally, fluoride ions, protects tooth structure from demineralization, a precursor of tooth decay.
    Type: Grant

    Inventors: Sabine H. Dickens, Frederick C. Eichmiller
  • Resin-based pulp capping and basing cements
    Patent number: 6398859
    Abstract: A pulp-capping and base/lining cement comprising the combination of paste 1 and either paste 2 or a powder, wherein paste 1 contains a carboxylated monomer, dicalcium phophate, and water; and paste 2 or the powder contains a polymerizable base monomer and tetracalcium phosphate. The cement is useful in the repair and/or restoration of dental lesions as well as repair and/or restoration of other calcium and calcium phosphorus containing parts of living organisms.

  • Single-solution adhesive resin formulations
    Patent number: 6210759
    Abstract: Single-solution adhesive resin formulations are made of predominantly dimethacrylates or diacrylates containing predominantly) two carboxyl groups and a functionalized methacrylate or acrylate diluent monomer. A novel light-activated initiator can be used for photopolymerization of such adhesives.

  • Single-solution adhesive resin formulations
    Patent number: 6206959
    Abstract: Single-solution adhesive resin formulations are made of predominantly dimethacrylates or diacrylates containing (predominantly) two carboxyl groups and a functionalized methacrylate or acrylate diluent monomer. A novel light-activated initiator can be used for photopolymerization of such adhesives.

  • Polymerizable conditioners for adhesive bonding to dentin and enamel
    Patent number: 6187838
    Abstract: The use of polymerizable monomeric conditioning agents for treating the enamel and dentin of a tooth prior to application of a primer and subsequent application of a bonding resin, or a combination of a primer/bonding resin has been found to provide good shear bond strength on both moist and dry dentin. In addition, the contact angles provided by water on dentin conditioned with the polymerizable conditioners as compared to the non-polymerizable phosphoric acid are much lower, reflecting improved spreading over the surface of the tooth.
